The current differential diagnosis for a short child with low insulin-like growth factor I (IGF-I) and a normal growth hormone (GH) peak in a GH stimulation test (GHST), after exclusion of acquired causes, includes the following disorders: (1) a decreased spontaneous GH secretion in contrast to a normal stimulated GH peak (“GH neurosecretory dysfunction,” GHND) and (2) genetic conditions with a normal GH sensitivity (e.g., pathogenic variants of <i>GH1</i> or <i>GHSR</i>) and (3) GH insensitivity (GHI). We present a critical appraisal of the concept of GHND and the role of 12- or 24-h GH profiles in the selection of children for GH treatment. The mean 24-h GH concentration in healthy children overlaps with that in those with GH deficiency, indicating that the previously proposed cutoff limit (3.0–3.2 μg/L) is too high. The main advantage of performing a GH profile is that it prevents about 20% of false-positive test results of the GHST, while it also detects a low spontaneous GH secretion in children who would be considered GH sufficient based on a stimulation test. However, due to a considerable burden for patients and the health budget, GH profiles are only used in few centres. Regarding genetic causes, there is good evidence of the existence of Kowarski syndrome (due to <i>GH1</i> variants) but less on the role of <i>GHSR</i> variants. Several genetic causes of (partial) GHI are known (<i>GHR</i>, <i>STAT5B</i>, <i>STAT3</i>, <i>IGF1</i>, <i>IGFALS</i> defects, and Noonan and 3M syndromes), some responding positively to GH therapy. In the final section, we speculate on hypothetical causes.

Most violence connected with sleep disorder is assumed to be related to sleep walking. It is less well known that other sleep disorders can also give rise to violence. The role of narcolepsy in car accidents is mentioned. Sleep drunkenness can lead to confusion resulting in violent behaviour especially on forced awakening. This condition is associated to sleep apnea. Primary or central sleep apnea is caused by disorders of the brain stem affecting the respiratory center. Secondary or upper airway sleep apnea can be caused by virtually any condition that results in cessation of the airflow due to occlusion of the upper airway. The author describes one patient who engaged in assaultive behaviour on forced awakening following earlier alcohol consumption. The pathomechanism of violent behaviour generated by a combination of sleep apnea and respiratory pathology is described. The differential diagnosis, prevention and treatment is outlined. The use of polysomnography in diagnosis and the potentially dangerous effects of drugs with respiratory depressing effects is highlighted.
